Just a quick one like, farmers abandoning their farms to move to cities. This is not recent. All those farms revert to jungle

"“There is far more forest here than there was 30 years ago,” said Ms. Ortega de Wing, 64, who remembers fields of mango trees and banana plants."

But what does someone who lives there know eh compared to you sitting on the internet

 

Annual deforestation in the Brazilian Amazon fell below 10,000 square kilometers for the first time since record-keeping began, reported Brazil’s Environment Minister Carlos Minc on Sunday.

Amazon rain forest biomass
n a report published in the 6 March 2009 issue of Science, Oliver L. Phillips of the UK's University of Leeds and his 65 co-authors write that "old growth forests in Amazonia ... through photosynthesis and respiration ... process 18 petagrams [18 x 1015 grams] of carbon annually," which they say is "more than twice the rate of anthropogenic fossil fuel emissions." They also state that over the past quarter-century of intensive region-wide measurements, the productivity of the Amazon rainforest -- even in its extreme old age -- has been found to be "increasing with time," in support of which statement they cite the comprehensive observational studies of Phillips et al. (1998), Nemani et al. (2003), Baker et al. (2004), Lewis et al. (2004) and Ichii et al. (2005).

Lets see you become an expert on this in 3 minutes. Go link hunting cos I have a bookmark folder called Rainforests.
Save the trees are full of ****

 

I'm fairly open minded about global warming. Not an expert but tend to rely on what the experts are saying.

Having said that, someone I know used a good analagy against the dangers of melting polar ice cap. He said the arctic pole is solid ice/snow. As such, if you imagine your glass of coke with ice in it. He used simple displacement theory that when the ice melts your coke doesnt rise. So this notion that the arctic ice melting will raise sea levels and cause flooding cannot be true.

 

The IPCC 2007 reports states there is been no trend in amazon rainfall over the 21st century.

So "global warming" is not "hurting" the Amazon either

 

Nearly all of the world's ice is in the south pole mate not the arctic. That ice been freezing for 10.000 years and is not adding to sea levels

The IPCC or "experts" hid the fact since 2008

 

I've asked you to back up that comment with some facts, educate me.......

As my opinion was that the rain forest reduction was very real and a genuine concern

You're stating that it's not an issue and I'd be very interested to read why this issue isn't an issue at all.so save your bullshit for until you've done so please.

If you come back with something that alters my view I'll happily concur.

 

@Treble 90% of earth's ice approx is in the south pole.

 

Not disagreeing where most of the ice is. But the claim for rising sea levels has always been cited as arctic ice melting.

 

You never ever alter your view ever.

The study supersedes your nat geo link

 

The arctic cannot rise sea levels, it's mostly land, not glacier. There is less than 5% of global ice in the arctic and it is all sea ice mostly. Much of it greenland and Greenland although melting a bit at the shores, is gaining 300 billion tons of ice per year

It's a MYTH

 

@Treble actually dont quote me on that less than 5%, I just threw that out there Just thought I'd point that out, go check it yourself.

 

There you go again.

I read that NY times link (what was that about you not taking anything from the media about climate change again?)

If you read it fully it clearly says that 38 million acres of rainforest are being logged every year. It's an interesting point about farm land being capable of reverting to rain forest, but in the short to medium term it's just scrub land with low height vegetation. It'd take decades to revert to full height canopy rain forest, and it still shouldn't stop the pressure to limit the destruction of the rain forest, as its reduction is responsible for 20% of the carbon dioxide increase.

 

Surely any deforestation has a massive impact on the ecosystem around it which often cannot be recovered even IF the forest grows back?

 

That analogy doesn't account for the melting of ice that is currently resting on land mass though.

 

Half of the actual rainforest estimated amounts of deforestation in Brazil came from one study that published in 1988 where a Brazilian scientist used US satellites to count the numbers of fires burning in the Amazon, a one time thing. This is where half the environmentalist estimates come from. Not even any kind of empirical measurement. Yes deforestation continues but not the danger to them we are all told.

The rest are environmental reports from single locations, not an actual study of total loss.

This was at the height of deforestation in Brazil which has declined since.

Amazon covers 6.5 million square kilometers, of which 3.5 million is in Brazil. Brazil created what is known as "Legal Amazonia" which covers nearly 5 million square kilometers, or 57 percent of Brazil’s territory. The entire continent of Europe could fit inside Legal Amazonia, and 70 percent of it is tropical forest.

 

Patrick Moore became an instant celebrity in 1977 when a photograph showing him cradling a baby seal in defiance of arrest by Canadian authorities was broadcast around the world.

As the front man for the environmental activist group Greenpeace, he helped turn public opinion around on the high-profile issues of whaling, seal hunting, nuclear power and chemical pollution.

Today the environmental scientist and leader of a group called Greenspirit has a new cause — alerting the public to what he calls the “myth” that the Amazon rainforest is endangered by development and deforestation.

Patrick Moore founded Greenpeace and left because it was hijacked by militant lefties.
He is now called a climate change denier. Humans as a reactionary group or herd suck ass, but not for "ruining the climate" and "destroying rainforest".

Again just post a link dont discuss it. Make a point or dont bother. Don't think you can just post a link and set me to reading it when you didnt.

How long have you looked into this subject, when I brought it up? few minutes? 3 minute expert
